Gases are not ionized while plasma is.
Transformation 3 should Tracy removed from the list. Chemical energy transforms into gravitational potential energy.
<h3> What is the law of conservation of energy?</h3>
According to the Law of Conservation of Energy, energy can neither be created nor destroyed, but it can be transferred from one form to another.
The total energy is the sum of all the energies present in the system. The potential energy in a system is due to its position in the system.
Transformations that occur as an engine runs to power a car is;
1. Chemical energy of fuel transforms into thermal energy.
2. Thermal energy transforms into electrical energy used to lighten the bulb in a car.
3. Thermal energy transforms into kinetic energy to help to run the car.
Chemical energy transforms into gravitational potential energy is the incorrect energy transformation.
Hence, transformation 3 should Tracy removed from the list.

The correct answer is
c) Neither person is correct because light does not change frequency when it travels through different media
In fact, light changes both wavelength and speed when it travels through different media, but the frequency remains the same.
The fact that a double convex lens is thicker across its middle is an indicator that it will converge rays of light that travel parallel to its principal axis. A double convex lens is a converging lens. A double concave lens is also symmetrical<span> across both its </span>horizontal<span>and vertical axis.

Answer:
a= 17.877 m/s² : Magnitude of the acceleration of the flea
β = 88.21° : Direction of the acceleration of the flea
Explanation:
Conceptual analysis
We apply Newton's second law:
∑F = m*a (Formula 1)
∑F : algebraic sum of the forces in Newton (N)
m : mass in kilograms (kg)
a : acceleration in meters over second square (m/s²)
Problem development
Look at the flea free body diagram in the attached graphic
The acceleration is presented in the direction of the resultant force (R) applied over the flea .
R= 10.905*10⁻⁶ N
We apply the formula (1) to calculate the magnitude of the acceleration of the flea
∑F = m*a m = 6.1 * 10⁻⁷ kg
R = m*a
a= R/m
a= (10.905*10⁻⁶) / (6.1 * 10⁻⁷ )
a= 17.877 m/s²
β: Direction and magnitude of the acceleration of the flea
β = 88.21°
